Review on 🔧 Dorman 788-522 Brake Line Adapter-Bubble Flare-M10-1.0 x 3/16 In. x M12-1.0: Reliable Solution for Brake Line Connection by Chris Jens

As another reviewer mentioned the 10mm socket is not machined for a bladder expansion caliper. It needs to be modified (with a drill) to properly seal the Bubble Flare port. The problem is that because the part is brass, it has a "brittle" finish and it's difficult to get a good enough finish for a hydraulic seal with a hand drill and vise in your garage. just know Otherwise, it seems to work well as an adapter. Two stars for an important Mi representation of the play!
